TLDR
The Cox-Lewis statistic leads to one-sided tests for regularity having reasonable power and provides a sharper discrimination between random and clustered data than other statistics.About:

Validating clusters using the Hopkins statistic
Amit Banerjee,Rajesh N. Dave +1 more
TL;DR: A novel scheme for cluster validity using a test for random position hypothesis is proposed, borrowed from the clustering tendency domain and its applicability to validating clusters is shown here using two artificially constructed test data sets.

Extension of the Cox-Lewis method for testing multi-dimensional data
Erdal Panayirci,Richard C. Dubes +1 more
TL;DR: A class of context-free languages is used to describe the fingerprint patterns and the recognition is accomplished using a sequential parsing technique to reduce the time requirement.

Two-dimensional discrete scan statistics☆
Jie Chen,Joseph Glaz +1 more
TL;DR: In this article, the authors investigated the accuracy of approximations for distributions of two-dimensional discrete scan statistics, including a product-type approximation, a Bonferroni-type inequality, two Poisson approximation, and a compound poisson approximation.

Experimental verification of parameters calculated with the statistical model of overlap from chromatograms of a synthetic multicomponent mixture
Scott L. Delinger,Joe M. Davis +1 more
TL;DR: In this article, a synthetic mixture of 56 hydrocarbons was prepared and partially resolved by capillary gas chromatography to experimentally test the predictions of the statistical model of overlap.
Fault detection in a network of similar machines using clustering approach
Jay Lee,Edzel Lapira +1 more
TL;DR: In this paper, a two-step approach is introduced: fleet clustering and local cluster fault detection, which verifies, discovers and identifies the group structure of the network of machines, and then the health of each unit in the cluster is assessed using peer-to-peer comparison.

Distance to Nearest Neighbor as a Measure of Spatial Relationships in Populations
Philip J. Clark,Francis C. Evans +1 more
TL;DR: In this article, the authors studied the vulnerability of several species to trapping on the islands and found that the islands appeared to lag behind the mainland in the development of their populations and the populations of small mammals fluctuate quite widely and the several populations appear to be somewhat independent of each other.
